Subject: [PATCH] Fix receipt rounding: round line items to cents before
 summing

Individual line prices were displayed rounded (via dollars()) but the
raw floating-point values were accumulated into the subtotal. This caused
totals like $0.99 instead of $1.00 when item prices had fractional cents.
